Abstract
(A1) Bei einem Verfahren zur duktilen Schleifbearbeitung sproedharter Werkstoffe, wird ein mittels eines Schleifwerkzeuges durchgefuehrtes duktiles Schleifen durch mindestens eine koerperschallunterstuetzte Schleifphase unterbrochen, in der das Schleifwerkzeug zu seiner zwischenzeitlichen Schaerfung und/oder Reinigung mit Koerperschall von mindestens 2 kHz beaufschlagt wird, wobei der Schleifvorgang stets mit einer duktilen Schleifphase endet. Das Verfahren kann so durchgefuehrt werden, dass die Prozesskraft einen kritischen Bereich (2) nicht erreicht.

 

DE 102007060973 A1 UPAB: 20090702 NOVELTY - The method involves interrupting a ductile grinding of glass executed by a grinding tool in an impact sound-supported grinding phase. The grinding tool is subjected to intermediate sharpening and/or cleaning with impact sound e.g. ultrasound, that is subjected to 2 kilo hertz, where the grinding process ends with a ductile grinding phase. Subjection of the grinding tool takes place with the impact sound in a rotation axis of the rotary grinding tool and in regular temporal distances. A process strength arising between the grinding tool and a workpiece is monitored. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a device for ductile grinding of brittle-rigid materials. USE - Method for ductile grinding of brittle-rigid material e.g. tungsten carbide, ceramics and glass ceramic or glass, in glass optics. Uses include but are not limited to camera objective, microscope, binocular, laser application, medicinal product and entertainment electronics in communication engineering, laser technology, automotive engineering and medical technology. ADVANTAGE - The method enables ductile grinding the brittle-rigid material to permit highest surface qualities without polishing process, thus saving the cost for grinding process.
